Having deployed my first application on a small home server which is sharing
the hosting of apache2 web server and tomcat, it is clear to me from
performance reasons that I need to serve as much static content as possible.
With this application I am able to serve the CSS and the images it refers to
statically because I can both map the css url over the top of the actual
place within the tomcat webapps directories where the file is stored, and can
use the .css extension (and the .gif extension for images) to jkUnmount these
particular elements of the servelet address space, thus leaving them to
apache to serve.
This css file has to be indentified to the @Shell component via an asset
declaration which I do in a "Border" component that I built via an annotation
in the associated java class of this Border component.
But I have found that if I declare the asset path as "/style.css" then by the
time it reaches the browser as html it has automatically added /xxxxx to the
front of it (where xxxxx is the application name).
However, I now want to develop a second application for my site (I need to do
this rather than just grow the first because the restart service is needed to
clear down a session and that sends you back to the application home page -
which needs to not be the sites real home page), using the same styles.
Obviously for site consistency (and maintainability during changes) I only
want one copy of the style sheet to exist.
I have discovered that if I enter the fully qualified url in to the asset
declaration (ie something like
@Asset("http://www.chandlerfamily.org.uk/style.css";) ) then this url does not
have the application name prepended.
HOWEVER - this is going to be a real pig to keep in step as I change from my
local pc testing environment to the server test environment and then onto the
final deployment.
Is it possible to actually tell the Asset to not add the application name to
the asset (or is there another way all together? I could imagine by border
component putting the html head in as static element and not using @Shell -
does it do anything important [Like generate the <base> element - is that
important?])
Advice please
